RE: EVFs ...too much engery consumption?
Unless the EVF is switched on and off, which is not as good as full time on optical finder, I dont see how the finder power could not be an issue. LCD displays draw maximum power at all times, even when image is all black.

In lens image stabilization, 10x optical zoom (38-380mm equivalent) and 2 megapixels of quality along with the EVF. Certainly not a convenient shape though with the protruding lens and box-like styling.

Re: EVFs ...too much engery consumption?
Well, the optical finders really are close to battery free, depending on the amout of zooming - and assuming the finder as zoom-capable. Taking DSLRs into account, the EVF replaces the entire mirror assembly, wich would present some battery use when winding - after each shot. Add some other bits saved and it is possible to close the gap somewhat. LF JC OConnell escreveu: wouldnt an EVF camera eat batteries even worse than flash?

I have no doubt that an EVF is orders of magnitude more power hungry than any mirror assembly...
